Frequently Asked Questions

Q: How do I know which riser mount to get?A: For AR's, we generally recommend the .83" mount, since it puts the red dot at basically the exact same height of Mil-spec iron sights. That means if you have a front sight, the red dot will be just at the point of the sight post. This is called "absolute cowitness"

Either of these mounts will work, it's really personal preference. For most people, the .83" mount seems to be the right choice, and it's the most popular. If you would like, you can get the 1" mount and it will sit a little higher than the iron sights. Now, if you have a front sight, it would appear in the lower 1/3 of the red dot sight's window. That is called "lower 1/3 cowitness"

Q: Do I need to use iron sights along with with the RD-50 Red Dot Sight?A: NO - Iron sights are not required to use this red dot sight! The red dot sight can be used on its own. Many people choose to use iron sights as a backup, but they are optional. This red dot sight will work great on "optics ready" rifles that don't have any iron sights.

Q: How are your prices so low?A: Since we sell AT3 products directly to the customer, vs selling through a distributor, we are able to pass savings on to you.

Customer Reviews

Fitted this sight to a custom Blackout build I've put together and very impressed with the fit, finish, and features. I'm very impressed with the sight, but have not had a chance to do more than get it sighted in at 25 yards. Weather is keeping me from going out and finishing my sighting in at the moment, but the first chance it gets above freezing I'm heading to the field. Can't wait to put it on paper!

Awesome little red dot sight. Works great.

I just mounted and put about 120 rounds through my AR15 with this sight. Worked great. Took some time to sight. I wish I would've bought the riser though. Also would be cool if the red dot similar to Eotech. Was hitting metal gong at 300 yards with this.

My First Red Dot

I searched all of the literature and found several reviews on this product. Best quality & best price for my needs. Put it on my Ruger 10/22 and it is great. Everything worked just as it was stated. Plan to get another soon for my AR.

Great entry-level optic

First red dot sight ever purchased. Have used others but priced out of my reach now. Needed a quality, inexpensive optic for my sight ready carbine AR. Easy to install & zero. Will pair soon with iron flip sights to cowitness and put the gear through it's paces. Crystal clear lens, nicely coated with no nicks or scratches, respectable 2 MOA dot for close range. Fastest shipping and delivery to Carolina I have experienced for FREE! Thank you AT3!

WOW! What a value!

I received the RD-50 about a week ago. Set-up was ultra easy. Sighting in took just a few minutes. I can't speak to long term durability yet, but this has to be the best value in a red dot sight in this price range. I sighted in and shot under bright skies - no problem picking up the dot under those conditions. Accuracy was right on the money every time. To top it all off (literally), this sight looks great sitting on top of a black gun. A small unit with lenses and controls large enough to use easily. This is my first RD-50, but probably not my last! AT3 Tactical and their products are spot on. Get one of these sights - you won't be disappointed.

RD-50 Sight

Great looking sight. I like the small size and it fits perfect. I like the fact that I can still use the iron sight if I choose to.

Good Sight - Great Price

Small and compact, mounted easily and securely to my AR-15. The fine 2MOA red dot is an improvement over other sights with larger dots. Available range of intensities are sufficient to cover all shooting situations. Easy to sight in and held zero all day through 100rds of 300BLK. Entirely adequate for much less than the cost of other 1x Red-Dot sights.

Wow, it actually worked!!!

I enrolled in a two day rifle training class (about 500 rounds each day) and really wanted to train with a red dot. Last year I used a 3x scope and have been in the market for a red dot for a while now. With the training only two weeks away and still not being ready to purchase something for $400, I found this red dot for $75 bucks. I took the gamble thinking if it fails, I'll just go with my backup iron sights and use the red dot's 3 year warranty.

IT WORKED THE WHOLE TIME! This little red dot kept up. All 1000 rounds, two days in the dirt. I didn't notice any problems. I got the medium riser so I could have absolute co-witness. I ran the whole thing at max brightness during the class. I'm glad I bought it, and I plan to use this for a good long while until I upgrade (think several years).

Zeroed and Ready to Go

Received my RD-50 Micro last week and got it zeroed at the range on Saturday. Very easy procedure. Dot works great on my M&P 15 Sport II. I got the 0.83" Riser and the Red Dot perfectly co-witnesses with the front sight post. I'm new to AR's and this Red Dot made the sighting effortless. I would definitely recommend the sight and by one for any other rifle I might buy.

The AT3 RD-50 Red Dot is a Steal!

I'm very happy with my purchase of the AT3 RD-50. I bought both riser mounts, but ended up using the .83" for absolute cowitness. This is the best red dot for the money... hands down. Worked great at the range. I had a question before ordering and their communication was quick, helpful and friendly. The shipping was very fast too.

Quality Optic

Really impressed with the quality feel of this AT3 Tactical Red Dot. Received shipping information immediately after placing the online order. With a 2MOA, I hope to add a magnifier soon to this setup and leverage it further out.

RD 50 Micro

Great little red dot. Was just what I was looking for - something compact and lite. Holds it’s setting on my 6.8 after repeated shots. Very Pleased with the sight. The optional mount was perfect height. Very little adjustment for zero. Another great purchase.

AT3 RD-50 outstanding value

Did a lot of looking around and research on red dot scopes and made the decision on the at3tactical rd-50. Now that I have tested it out I'm convinced I made the right choice.
Set up was quick, zeroed in right away. Meets all my concerns. Excellent website, quick professional ordering. Everything as advertised.
Well done. If your in the market for red dot scope, pull the trigger here.

Eager for this to arrive

It's been nearly two weeks since I ordered this. Supposed to arrive tomorrow. I suspect it's a fine little optic for the money, just one crazy delivery process. First it sat for six days in Fort Dodge, IA then over the course of one day's it arrived and left several times in Kansas City. Not AT3's fault but crazy "first class" mailing.

Looks good so far

Shipping was quick. Optic easily mounted to upper with .83" riser and appears to function properly. This is a part of my first ever build and I didn't want to break the bank so this suited my needs. Once I shoot the rifle and zero it, I'll update, but happy so far!

Fast service. Received the day after I ordered. Rugged build, good looks, crisp clear bright dot. Took it to work for "show and tell" and two of my friends ordered one.

Precision/Quality

Firearm used- AR-15
Good field of vision weather mounted forward or rearward with a precise Red Dot. Mounts are solid, and install easy. Red Dot adjustable range is more than sufficient. My overall opinion is this sighting system is a good quality package at an affordable price.

Nice quality, easy to mount, solid product and functions great! Very good buy for an optic under $100. Would definitely buy this item again.

Great bang for the buck

I've only taken this sight to range once but was very pleased. After a few hundreds rounds it stayed solidly mounted and zero was perfect still. The second part of my range trip was a bowling pin shoot and it was very easy to pick up the dot even in the bright of day. Great sight at a great price.

Great Red dot sight.

Installed on Anderson flattop build, perfect co witness with LWRC flip ups with the .83 riser. Couldn't be happier. + it was on sale!

TRS-25

From the experience I've had with this sight thus far It seams almost exactly the same as the Bushnell trs-25 which is not a bad thing. I love the Bushnell trs-25s I own 4 3 of them. This dot seemed slightly brighter on the AT3 on the lowest setting. The only complaint is that the AT3 is advertised as a 2 moa and while I have no way of measuring it to my naked eye it was just as big of a dot as the trs25 which is advertised as a 3 moa dot.
